$500 mn Vulnerability In Tron Multisig Accounts
A dWallet Labs research team uncovered a zero-day vulnerability in Tron multisig accounts, allowing an attacker to circumvent the multisignature process and sign transactions with a single signature.
The research team stated in a technical breakdown article that the issue could have affected $500 million in funds kept in Tron multisig accounts. This is due to the fact that it allows any signer to “completely overcome the multisig security offered by TRON.”
Multisignature wallets, as the name implies, require many signers defined in an account to approve transactions and move funds, allowing the creation of joint accounts in cryptocurrency. Each account signer has their own key, and the account requires a particular threshold for transactions to be approved.
